COAL-WAGON.

SPECIFICATION forming part of Letters Patent No. 558,590, dated April 21, 1896. Application filed January 6, 1896. Serial No. 574,441. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE B. MARX, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Coal- WVagons, &c. of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

Devices of great variety have been suggested hitherto and have been used for the purpose of facilitating the unloading of coal or other material from trucks or wagons and from railway-cars. In some cases the body of the wagon is arranged to be elevated and tilted; but this construction is not available for railway-cars or even for the large and heavy trucks which are now commonly used. In other cases the bottom of the body is inclined toward the point of delivery sufficiently to insure a free movement of the coal or other material when unloading, and the delivery chute is arranged sometimes at the end of the body, but more often and preferably at a central point, so that it does not become necessary to back the wagon or truck up to the point where the coal or other material is to be delivered, but permits it to be drawn up alongside the curb or wall. I11 this case it becomes desirable to provide for the delivery of the coal or other material from either side of the wagon or truck; and it is in improved means for this purpose and for controlling the delivery of the coal or other material that my present invention consists.

The novel features of construction will be fully described hereinafter with reference to the accompanying drawings, in which- Figure 1 is a side elevation of a coal truck or wagon to which my improvements are applied. Fig. 2 is a section on the line :1: cc of Fig. 1, with the parts in position for the delivery of the coal at one side of the truck or wagon. Fig. 3 is a similar view on the line 1 y of Fig. 1, with the parts in like position. Fig. 4C is a detail view of a portion of the delivery devices in section on the plane indicated by the line a z of Fig. 5. Fig. 5 is a detail sectional View of the same parts in a plane at right angles to that of Fig. 4, and Fig. 6 is a plan view of one end of the delivery pan or trough and its swinging door.

The body A of the wagon or truck is conend or the other dropped.

structed in any suitable manner, with the bottom inclined from the ends toward the middle portion to facilitate the movement of the coal toward the transverse opening a, and it is supported upon the running-gear in any suitable manner. At each side of the opening a is secured a cheek-piece B, which depends a short distance below the bottom of the body, each cheek-piece being preferably cut away at the lower corner, as at Z). Between the cheek-pieces is disposed a tilting pan or trough O, which has at each end short oppositelyprojecting lugs or pins 0 c, which enter corresponding slots d d in the normally horizontal arms or wings (Z d, formed upon or secured to a swinging plate or door D. The latter is hinged to the body of the wagon, as at 01 and is normally held with the arms or wings cl cl horizontal, thereby supporting the pan or trough O in a horizontal position. Each plate D, with its arms or wings cl d, is, however, adapted to swing into a position represented at the left in Figs. 2 and 3, thereby permitting the corresponding end of the tilting pan or trough O to drop down and permit movement of the coal outward in a corresponding direction, the other end of the pan or trough 0 being held in its elevated position by the engagement of its pins 0 c in the slots cl d of the other pair of wings or arms (1 cl, which. are still held in their horizontal position.

Zach plate D is provided with an aperture (1 to receive a tongue 0, which projects from the corresponding end of the pan or trough O. The tongue 0 also has an eye 0 to receive a pin 0 which prevents the accidental release of the pan or trough (1.

It is obvious that the chief function of the plates or doors I) D, with their slotted arms or wings d cl, is to permit the necessary tilting of the pan or trough O, and to permit it to be sustained in a horizontal position, or with one To control the 9 5 movement of the coal and also to enable either end of the pan or trough C to be raised when required, as well as to hold it up when raised, I provide at each end of the opening a a vertically-sliding gate E, which is formed with a hook e to engage the corresponding end of the pan (J. Each gate E preferably has secured thereto a rack F, which slides in a suitable guide f, secured to the side of the body A, and

is engaged by a pinion f fast on a short shaft f. The latter is supported in a suitable bearing in the side of .the wagon-body A and is formed, as at f for engagement bya suitable crank, by which the rotation of the shaft may be effected. The shaft is also preferably provided with a ratchet-wheel f, which is e11- gaged by a hold-pawl f 5 to prevent backward rotation of the shaft. The hook e on the gate E is preferably arranged to project through a hole 0 in the bottom of the pan or trough C and to engage a bolt G, which is supported in suitable brackets g to slide longitudinally, is pressed forward by a spring g, and is provided with a suitable handle g by which it maybe released from the hook 6 when required. The hook e and the bolt G are suitably beveled, so that the engagement of the two may be effected automatically.

In suitable hangers a which are secured to the bottom of the wagon-body, are supported the usual telescoping chutes II II, the outer chute H preferably being provided with hooked fingers h h at each end, which, as the chute is drawn out, are adapted to engage the pins 0 c of the depressed end of the pan or trough C, as shown clearly in Fig. 2, to prevent the drawing out of the chute too far. The pin before referred to, is made long enough to stand across the ends of the chutes H H as they are in place in the hangers a and prevent their accidental displacement.

Before the wagon is loaded the pan 0 is sustained in a horizontal position by the engage ment of the vertically-movable gates E E with the bolts G G by means of the hooks c c, the gates themselves being held in position by the engagement of the hold-pawls with the ratchet-wheels on the shafts which carry the pinions f f, the gates E E at the same time preventing the outward movement of the coal against the swinging doors or plates D D. \Vhen the wagon has been loaded and it is de sired to deliver coal at one side or the other, the pin 0 at the proper side is pulled out of the eye 0 of the tongue 0, which projects from the pan 0 through the hole in the corresponding plate or door D, thereby permitting the said door or plate D to be swung outwardly. The bolt G may then be disengaged from the hook 6, thereby permitting the end of the pan 0 to drop, which movement of itself will cause the door D to swing into the position shown at the left in Figs. 2 and S, or the end of the pan may be lowered more gently by lowering the gate E without disengaging the bolt G therefrom until the end of the pan has reached its lowest position. Finally, the gate E is drawn up to the desired extent to permit the movement of the coal outward through the pan 0.

If it is desired at any time to stop the movement of the coal, the gate E is lowered until the hook c engages the bolt G, at the same time stopping the movement of the coal. The gate is then raised partly, lifting with it the end of the pan or trough C until it is once more in a horizontal position, and at the same time the plate D swings back to its normal position, the tongue 0 of the pan or trough Gentering the hole 01 and the pin 0 being replaced the pan is therebysecured in its horizontal position.

It will be understood that while I have herein described my improvements as adapted specially for use with coal-wagons, nevertheless I do not intend thereby to restrict the invention to any particular use, inasmuch as the improvements are obviously applicable to coal-cars and to wagons, trucks, or cars for transporting and delivering material other than coal. It is also to be understood that I do not intend to limit my invention to the precise construction and arrangement of parts which are herein shown and described.

That I claim, and desire to secure by Letters Patent, is

1. The combination with a body of a coal or other wagon having a delivery-aperture in its bottom, of a delivery-pan arranged below said aperture and extending from side to side of said body, slotted arms connected to said body and engaging said pan at the ends thereof, whereby either end is permitted to drop to a limited distance, and vertically-movable gates carried by said body and adapted to be lowered and raised to prevent and permit the movement of coal outward through said pan, substantially as shown and described.
